I can see that my Canon EOS 400D and I are going to get on swimmingly!
UPDATE: It seems MacOS X 10.4.8 doesn't support the RAW images generated by the EOS 400D/Rebel XTi… Grrr…
UPDATE 2: There's now a "RAW Support Update" available for the Canon EOS 400D/Rebel XTi. Woohoo! (Check the Aperture page for links.)
